super austenitic stainless steel
Super stainless steel is a special kind of stainless steel. First of all, it is different from ordinary stainless steel 304 in chemical composition. It refers to a high alloy stainless steel containing high nickel, high chromium and high molybdenum. Secondly, in terms of high temperature resistance or corrosion resistance, compared with 304, it has better high temperature resistance or corrosion resistance and is irreplaceable. In addition, from the classification of stainless steel, the metallographic structure of special stainless steel is a stable austenite metallographic structure.
The concepts of super austenitic stainless steel include super ferritic stainless steel and super duplex stainless steel. Typical examples are super austenitic stainless steels containing 6% and 7% molybdenum. These steel grades were developed for harsh industries such as petrochemicals, chemicals, paper and offshore systems.
